As dogs mature, their eating habits can shift in some surprising ways.

Their caloric needs decrease, but they may become more finicky eaters.

Research shows that dogs over 7 years old tend to eat less than younger dogs.

This can be due to a decrease in muscle mass and metabolism.

Some dogs may also experience dental issues, making mealtime more challenging.

Older dogs often require more protein in their diet to maintain muscle mass.

This is especially true for larger breeds, which can lose muscle mass quickly.

Nutritional Changes

As dogs age, their nutritional needs change. Probably the most important thing is that their energy requirement gets lower, making them more likely to become overweight or obese.

Many dog food companies now offer senior dog food formulations, which are lower in calories and suitable for older pets. These foods are a great option for owners who want to ensure their senior dog is getting the right nutrition.

Senior dogs need to drink more water as they age, as their body's ability to maintain water balance decreases. Encourage your senior dog to drink plenty of water throughout the day.

Dogs may need more protein as they age, but the optimal amount is still a topic of discussion. Higher protein quality is important, but it's essential to re-evaluate the protein and phosphorus levels in your dog's diet if their kidney function is compromised.

Excessive sodium in the diet can contribute to kidney disease and hypertension in senior dogs. Your vet may suggest purchasing commercial treats that reflect the nutrient balance of your dog's chosen senior diet.

Here are some healthy snack options for senior dogs:

  • Water-based vegetables like green beans, carrots, cucumbers, broccoli, and lettuce
  • Small servings of apples, bananas, oranges, or various berries served fresh or frozen
  • Low-calorie treats containing fewer than 10 calories per piece

Every dog digests foods differently, no matter their age. If your senior pet doesn't seem to be taking to a particular food, it may be time to try something different.

Weight and Health

As dogs age, their eating habits can change significantly. Weight changes in senior dogs can have a huge impact on their life, increasing the risk of conditions like arthritis, diabetes, and heart disease.

Weight gain is common in senior dogs due to decreased activity, but it's essential to adapt their food accordingly. Losing weight in senior dogs is usually linked to a medical issue.

Senior dogs with medical problems may require special diets to help manage their conditions. A veterinarian or veterinary nutritionist can help plan a proper diet for dogs with diabetes, kidney failure, or liver disease.

Dogs with heart disease may need lower-calorie senior dog foods to help keep weight down, and lower-sodium formulations are also recommended.

Health Problems Affecting Diet

As your dog ages, they may develop health problems that require special attention to their diet. Weight changes can have a huge impact on a dog's life, increasing the risk of conditions like arthritis, diabetes, and heart disease.

Dogs with diabetes may need a special diet that slows down the absorption of food to prevent a spike in blood sugar. Lower-fat, higher-fiber foods are best for diabetic dogs.

Senior dogs with kidney failure, liver disease, or heart disease may require special veterinary diets to help manage their conditions. These diets may include lower-calorie foods to keep weight down and lower-sodium formulations.

If your senior dog has trouble with constipation, a higher-fiber diet can help them stay regular. Many senior diets have higher-quality protein sources to maintain body weight and muscle mass without straining the kidneys.

Differences vs Regular

Some dog foods labeled as "senior" or "all life stages" might be identical, with only the packaging changing. This lack of regulation can cause confusion.

Nutrient adjustments are one key difference between senior dog food and regular adult dog food. This can help manage the physical and medical changes dogs experience as they age.

Higher digestibility is another factor that might be included in senior dog food. This can be especially helpful for older dogs with sensitive stomachs.

Softer texture and added joint supplements are also common in senior dog food. These features can help with dental health and joint mobility.

Some senior dog foods include added MCTs, omega-3s, and antioxidants. These nutrients can provide extra support for older dogs' overall health.

Switching to a diet for your senior dog requires careful consideration, as there are no established nutrient requirements for senior dogs.

Most senior dog foods are less calorie-dense than rations for puppies and young adults, which can help with weight management.

Your veterinarian is your best resource when choosing a diet for your senior dog.

Senior dogs with medical problems, such as diabetes, kidney failure, or liver disease, may require special veterinary diets.

Lower-calorie senior dog foods can help dogs with heart disease manage their weight and overall health.

Lower-sodium formulations can also be beneficial for dogs with heart disease.

A diabetic diet should aim to delay the absorption of food, which can help regulate blood sugar levels.

Lower-fat, higher-fiber foods are best for diabetic dogs, as they help slow down the absorption of food.

A higher-fiber diet can also help senior dogs with constipation stay regular.

Many senior diets feature higher-quality protein sources, which can help maintain body weight and muscle mass without straining the kidneys.

As dogs age, their eating habits can change significantly. Some senior dogs may experience reduced appetite, which can be caused by various factors such as gastrointestinal problems or cancer.

A veterinarian should rule out any underlying health problems before trying to stimulate appetite. This includes checking for dental disease, diabetes, kidney disease, or cancer.

Some owners find that adding warm water, chicken broth, or a small amount of canned food can make dry food more appealing to their senior dogs. Home-cooked meals can also be enticing, especially if they're made with extra TLC.

Signs of aging in dogs include vision problems, lumps and skin issues, weight loss or gain, and bad breath or excessive drooling. As dogs enter their geriatric years, they may exhibit more severe symptoms such as memory loss, altered behavior, or impaired mobility.

Here are some common signs of aging in dogs:

  • Vision problems;
  • Lumps and other skin issues;
  • Weight loss or gain;
  • Bad breath, excessive drooling, or other dental symptoms;

Regular checkups with a veterinarian are essential to detect changes in organ function or other internal issues. Most vets recommend twice yearly visits for senior dogs to monitor their health and make recommendations on nutrition and diet.

Dental Issues

As your furry friend ages, dental issues can become a pressing concern. Senior dogs are particularly susceptible to periodontal disease due to a lifetime of wear and tear on their teeth.

You can help prevent dental issues by brushing your senior dog's teeth once a day with a dog-safe toothpaste. Regular check-ups with your veterinarian are also crucial, with a minimum of every 6 months recommended.

If your senior dog has lost teeth or has loose or infected teeth, switching to a soft food can make mealtime easier. Canned, raw, or fresh food is often a better option than kibble, which can be tough for dogs with dental issues to chew.

Some dog food products specifically marketed for dental disease may be just regular foods with added moisture. However, some products do contain ingredients that can help combat oral problems.

Here are some common ingredients found in dog food products that aim to combat dental disease:

  • Sodium hexametaphosphate or citric acid, which help prevent minerals from sticking together and forming calculus (hard, rock-like material on teeth)
  • Dog probiotics, aka healthy bacteria, which may play a role in oral health

At What Age?

Dogs age faster than humans, and their life expectancy varies greatly depending on their breed and body weight. Large and giant breeds age faster than smaller dogs.

As a general rule, dogs are considered older when they've reached half of their life expectancy. For example, small breeds like little dogs live to about 15 to 20 years of age, while bigger dogs live to about 12 to 15 years.

Bigger dogs are considered older at around six years, and smaller dogs become older at around eight or nine. However, certain breeds age faster than others, and giant breeds might start developing senior health issues, especially arthritis, at 5-7 years old.

Here's a rough guide to help you estimate your dog's age:

Keep in mind that every dog is different, and monitoring your pet for changes in behavior or symptoms of illness is the most important thing, regardless of age.

Signs of Aging

Vision problems are a common sign of aging in dogs, and can manifest as cloudy eyes, cataracts, or even blindness.

Lumps and other skin issues can also be a sign of aging, and may be caused by skin cancer or other conditions.

Weight loss or gain can be a sign of aging, and may be caused by a variety of factors, including changes in appetite or metabolism.

Bad breath, excessive drooling, or other dental symptoms are also common signs of aging in dogs.

Here are some specific signs of aging to watch out for:

  • Vision problems;
  • Lumps and other skin issues;
  • Weight loss or gain;
  • Bad breath, excessive drooling, or other dental symptoms.

As your dog gets older, they may start to show more severe signs of aging, including memory loss, altered behavior, and difficulties following their normal sleep patterns.

Loss of muscle mass, increased urination, and urinary incontinence are also common signs of aging in dogs.

Osteoarthritis and impaired mobility can make everyday activities more challenging for your dog.

Regular checkups with your vet are essential to monitor your dog's health and catch any potential issues early.

Supplements and Care

As dogs age, their eating habits can change, and they may benefit from certain supplements to support their health. Large breed dogs, in particular, may require extra care in their diet due to their unique needs.

If your senior large breed pet is experiencing digestive difficulties, your vet can help suggest a food with extra insoluble fiber, such as green beans or broccoli, which can be beneficial. This type of fiber is different from soluble fiber, which can worsen stool quality.

Some supplements that may be beneficial for senior dogs include MCTs, DHA, and antioxidants. MCTs, a type of fat found in coconut oil or palm oil, can help support brain health, while DHA, an omega-3 fatty acid, can help reduce the symptoms of arthritis. Antioxidants, such as carotenoids and other phytonutrients, can also help reduce the effects of aging.

A reasonable starting amount of DHA is 0.5 grams per 1,000 calories, and some senior dog foods contain glucosamine and chondroitin sulphate to help with joint health. However, it's essential to use veterinary formulations of these supplements, not human ones.

Added MCTs, DHA, and Antioxidants

As your furry friend ages, you may notice changes in their memory and ability to learn. Adding certain nutrients to their diet can help reduce some of these effects. Medium-chain triglycerides (MCTs), found in coconut oil or palm oil, can be a helpful addition.

A diet rich in antioxidants, like those found in veggies, can also support your dog's health. Carotenoids, such as beta-carotene, are a great example of these beneficial compounds. You can even add MCTs and antioxidants to your dog's food as a supplement.

DHA, an omega-3 fatty acid, is another nutrient that can make a big difference. It's found in high concentrations in fish and algae oil, and can be added to your dog's diet as a supplement. A reasonable starting amount is 0.5 grams DHA per 1,000 calories.

Here are some key points to keep in mind when adding MCTs, DHA, and antioxidants to your dog's diet:

  • MCTs can be found in coconut oil or palm oil, or added as a supplement.
  • Antioxidants like carotenoids and phytonutrients can be found in veggies and added to your dog's diet.
  • A reasonable starting amount of DHA is 0.5 grams per 1,000 calories.

Should Take Supplements?

Should your senior dog take supplements? Many older dogs struggle with arthritis and joint pain.

Glucosamine and chondroitin sulphate can be found in some senior dog foods to help with joint issues. However, owners should use veterinary formulations, not human ones, if they decide to give their dogs glucosamine and chondroitin supplements.

Dogs with joint problems and arthritis benefit more from slimming down than from glucosamine supplements. People often think glucosamine is the best solution, but weight management is actually the most effective way to alleviate joint pain.

Frequently Asked Questions
